A flattish rather wide species much narrowed at both ends, 

 not unlike S. mustela-major, Thoms,, in outline save that the- 

 sides of the prothorax are much less rounded ; the shape of this 

 segment — narrow in front with sides diverging from the front 

 almost to the base itself in almost straight lines — is unusual in 

 the genus. This character in combination with the colouring — 

 entirely of a blackish or metallic colour except the elytra and 

 abdomen which are entirely pale testaceous — will, I think, dis- 

 tinguish the present species satisfactorily. I have seen several 

 examples which vary inter se only in respect of the darkly 

 coloured parts being coppery or green or blackish as the case may 

 be.
